CRITICALFix: jenkinsci/plugin-installation-manager-tool@dfc745cGHSA-m8r4-c7jm-w782 is a critical-severity (CVSS 9.8) CWE-494 vulnerability in io.jenkins.plugin-management:plugin-management-parent-pom. A fix is available for io.jenkins.plugin-management:plugin-management-parent-pom — see the affected versions and patch details below.
Jenkins Plugin Installation Manager Tool did not verify plugin downloads
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-m8r4-c7jm-w782 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,166 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure
io.jenkins.plugin-management:plugin-management-parent-pomReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Jenkins Plugin Installation Manager Tool is part of the Jenkins project Docker images. As jenkins-plugin-cli it is used to download and install plugins even before Jenkins is running.
Jenkins Plugin Installation Manager Tool 2.1.3 and earlier does not verify plugin downloads. This may allow third parties such as mirror operators to provide crafted plugin downloads.
Jenkins Plugin Installation Manager Tool 2.2.0 confirms that actual checksums of downloaded plugin match the expected checksums.
Docker images of Jenkins 2.269 and 2.263.1 contain Plugin Installation Manager Tool 2.2.0. Users of older Docker images can change the version they use by extending the Jenkins image and update the tool themselves with:
ARG PLUGIN_CLI_URL=https://github.com/jenkinsci/plugin-installation-manager-tool/releases/download/2.2.0/jenkins-plugin-manager-2.2.0.jar RUN curl -fsSL ${PLUGIN_CLI_URL} -o /usr/lib/jenkins-plugin-manager.jar Jenkinsfile Runner 1.0-beta-22 Docker images also include Plugin Installation Manager Tool 2.2.0.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.jenkins.plugin-management:plugin-management-parent-pom, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update io.jenkins.plugin-management:plugin-management-parent-pom to 2.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-m8r4-c7jm-w782 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-m8r4-c7jm-w782 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-m8r4-c7jm-w782. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-m8r4-c7jm-w782 in your dependencies?
O3 Security finds GHSA-m8r4-c7jm-w782 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
